Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The present invention proposes a high-gain and high-directivity metamaterial microstrip antenna based on a double hexagonal ring structure. Its specific structure is: a supersurface resonator 1, an upper cladding dielectric substrate 2, The microstrip patch 3, the coaxial feed probe 4, the antenna substrate 5 and the metal grounding plate 6, the microstrip patch 3 and the metal grounding plate 6 are mounted on the upper and lower surfaces of the antenna substrate 5 respectively, and the microstrip patch 3 A coaxial feeding probe 4 is provided.

[0023] The metasurface resonator 1 is composed of 24 metamaterial units, and the 24 metamaterial units are arranged in a 4×6 manner. There is no gap between two metamaterial units arranged horizontally, and there is a gap between two metamaterial units arranged vertically. The metamaterial unit is composed of...

Abstract

The invention relates to the technical field of communication antennas, in particular to a high-gain high-directivity metamaterial microstrip antenna based on a double hexagonal ring structure. Two regular hexagonal metal copper rings which are same in size, are horizontally arranged and connected together are used as metamaterial units; a plurality of metamaterial units which are located on the same horizontal plane and are transversely connected and longitudinally disconnected form a metasurface resonator, the metasurface resonator is bonded to an upper coating dielectric substrate to serveas a metamaterial upper coating, the metamaterial upper coating is loaded on a coaxial feed microstrip antenna, and the high-gain high-directivity metamaterial microstrip antenna is formed. The coaxial feed microstrip antenna comprises a microstrip patch, a coaxial feed probe, an antenna substrate and a metal grounding plate, the microstrip patch is located in the middle of the antenna substrate,and the coaxial feed probe is arranged on the microstrip patch (3). Due to a Fabry-Perot resonant cavity effect, the higher reflection characteristic of the metamaterial is beneficial to enhancing thegain of the antenna.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to the design of a high-gain and high-directivity metamaterial microstrip antenna based on a double hexagonal ring structure. Background technique [0002] Due to the advantages of low profile, small size, low cost, and easy integration, microstrip antennas have become the main choice in modern wireless transmission systems such as microwave, radar, and communication applications. However, conventional microstrip antennas have limited their widespread use due to the disadvantages of low gain, poor direction, and narrow bandwidth. Therefore, improving the gain and bandwidth of the antenna has become a research hotspot, and the research on the microstrip antenna is constantly innovating and developing. Several techniques have been proposed to increase the gain and improve the performance of the antenna. [0003] Metamaterial is a sub-wavelength artificial composite mat...
